Title: Artificial ground and construction method of shed thereof
Inventor: IZUMI YUJI
IPC: E02D27/12
Filed: 1993-12-20
Abstract: PURPOSE:To construct an artificial ground in advance and build a shed on the completed ground, by separately designing the artificial ground and the shed after having unified the artificial ground with the shed as a unit and given the story shear coefficient due to an earthquake thereto. CONSTITUTION:A simulation is carried out against a unit consisting of an artificial ground and a shed so as to obtain the story shear coefficient due to an earthquake. Next, the artificial ground is separated from the shed and the stresses of column bases are calculated under the condition that the shed is fixed on the column legs on the basis of the story shear coefficient so as to advance design the artificial ground. On the other hand, the shed separated form the ground is designed as an ordinary building. In this case, when the artificial ground, part is constructed, joint metal fittings 2 regarded as the shed columns are previously attached to the top of a steel pipe pile 1. In this way, the upper and the lower structures are separated from each other in both design and construction and the shed is designed in the same method with a shed erected on an ordinary natural ground. And both designs are simplified by only summing up the load-weight of the artificial ground itself or the like. In this way, the construction is facilitated and the erection period can be reduced.

Title: Thin-film magnetic head
Inventor: YODA HIROAKI
IPC: G11B5/31
Filed: 1988-12-19
Abstract: PURPOSE:To improve mass productivity and to obtain good head characteristics by forming an imidization accelerating layer as an underlying film for a polyimide layer between a substrate contg. a coil and the polyimide layer. CONSTITUTION:The imidization accelerating layer 52 consisting of glass contg. an alkaline metal is formed as the substrate of the polyimide layer 53. The alkaline metal of the imidization accelerating layer 52, therefore, diffuses into the polyimide layer 53 to accelerate the imidization of the lower layer part at the time of prebaking of the polyimide layer 53. The polyimide layer 53 having the higher rate of the imidization in the lower layers is thus formed. Etching of the polyimide layer 53, therefore, progresses faster in the upper layer of the lower rate of imidization and slower in the lower layer of the high rate of imidization. The edge part of the polyimide layer 53 is thus tapered to a prescribed angle and the wall formation of the magnetic layer to be formed on the polyimide layer 53 is possible. The mass productivity is improved in this way and the head characteristics are upgraded.

Title: Measurement of beam diameter or beam edge resolution
Inventor: SUZUKI SHOHEI
IPC: G01T1/29
Filed: 1988-12-20
Abstract: PURPOSE:To enable picking up of an effective signal without being affected by noises by setting an angle theta between a direction of scanning and a tangential to an interface at a value sufficiently less than 90 deg.. CONSTITUTION:An electron beam 7 is deflected with a deflector 1 wherein an applied voltage is changed repeatedly in continuity with a deflection controller 11 with a deflecting voltage controlled by a command from a computer 10 and scans traversing a gold fine line 2 (gold wire 2) so arranged that a diameter position thereof coincides with a height the same as a focal position 3. A relationship between axis-of-abscissa dimensions on a CRT 5 and a moving distance of the electron beam 7 on a focal plane 3 is determined from a thickness (h) of the gold wire 2 and a distance X0 at which a waveform on the CRT 5 traverses 50% at the level thereof. Thus, a beam diameter of the electron beam can be determined by X1/X0h cosec theta. In this case, as a scanning distance is longer by a consec theta factor as compared with the case where the electron beam scans at the right angle of the gold wire 2, higher resolutions are achieved. On the other hand, this results in a larger range of change in a scanning voltage of the deflector 2 thereby making effect of noises hard to suffer.

Abstract: PURPOSE:To detect a microdefect in a body to be inspected which has a curved surface of less than tens of mm in diameter by using a probe having a tip part which has a curved surface of the same kind with the curved surface of the body to be inspected and has a radius of curvature 0.5 - 2.0 times as large as that of the body to be inspected. CONSTITUTION:The probe 1 conforming with the curved surface of the body 2 to be inspected, e.g. an acoustic lens at the tip part of the probe 1 facing the body 2 to be inspected or a probe 1 with a spherical vibrator is used when the body 2 to be inspected is spherical to perform ultrasonic inspection. At this time, when the radius of curvature of the tip part of the probe 1 is <=0.5 time as large a the radius of curvature of the curved surface of the body 2 to be inspected, an ultrasonic wave is focused nearby the surface of the body 2 to be inspected, and consequently its internal detection ability becomes inferior. When the radius of curvature is >=2.0 times, the ultrasonic wave is scattered by the surface of the body 2 to be inspected, which is not preferable. For the purpose, the radius of curvature of the tip part of the probe 1 is set 0.5 - 2.0 times as large as that of the curved surface of the body 2 to be inspected and then the ultrasonic wave is incident on a flaw detection surface without being scattered by the surface to detect the defect of the body 2 having the curved surface of less than tens of mm in radius of curvature.
